Introduction to Health Promotion & Disease Prevention
Key concepts, frameworks, and practical strategies for improving population health.
| Term | Meaning |
|---|---|
| Health Promotion | The process of enabling individuals and communities to increase control over, and improve, their health. It goes beyond disease prevention to include well‑being, empowerment, and healthy lifestyle choices. |
| Disease Prevention | Activities that aim to reduce the incidence, severity, or recurrence of specific illnesses. It is often categorized into primary, secondary, and tertiary levels. |
| Public Health | The science and art of preventing disease, prolonging life, and promoting health through organized community efforts. |
| Level | Goal | Typical Interventions |
|---|---|---|
| Primary | Prevent disease before it occurs | Immunizations, health education, legislation (e.g., tobacco bans), environmental sanitation |
| Secondary | Detect disease early and intervene promptly | Screening programs (mammography, blood pressure checks), early treatment, health‑risk assessments |
| Tertiary | Reduce complications and improve quality of life for those with established disease | Rehabilitation, chronic disease management programs, support groups, palliative care |
| Theory / Model | Core Idea | Relevance to Practice |
|---|---|---|
| Ottawa Charter (1986) | Health promotion is built on five action areas: building healthy public policy, creating supportive environments, strengthening community action, developing personal skills, and reorienting health services. | Provides a global framework for policy‑level and community‑based initiatives. |
| Social Ecological Model | Health behavior is influenced by multiple layers: individual, interpersonal, organizational, community, and policy. | Guides multi‑level interventions that address both personal and environmental determinants. |
| Health Belief Model | People act based on perceived susceptibility, severity, benefits, barriers, cues to action, and self‑efficacy. | Useful for designing targeted education and behavior‑change campaigns. |
| Transtheoretical (Stages of Change) Model | Behavior change progresses through precontemplation → contemplation → preparation → action → maintenance. | Helps tailor interventions to an individual’s readiness to change. |
